Help. Won't install roms from recovery

Has been trying to install official CM9 nightlies and some other roms but installation aborts. Did wiping cache partition, wiped/factory wiped and dalvik cache wiped 3 times. Did everything I knew but nothing seems to work. Been rooting and flashing roms for G1's, N1, G2X, nook colors, atrix 4g, HP TouchPad. Just sold my touch pad and just rooted this galaxy wifi 10.1.
Help please...
